TO ALL WHOM IT MAY CON CERN:

Be it known that I, AncHIBALD H. C. BARBE'R, 4of Clinton, De Witt county, State of Illinois, have invented a. new and useful Improvement in Grain Dryer; and I do hereby declare that the following is a full, clear, and

exact.A description thereof, which will enablel others skilled in the art to make and use the same, reference beinghad to thelaccompanying drawing, forming part of this speciication,.in Which- Figure l is a top or plan view of my improved grain dryer, parts being brolien away to show the construction. Figure 2 is a vertical longitudinal section of the drying kiln taken through the line :v x, tig. 1. Figure 3 is a vertical longitudinal section of the furnace taken through the line y y, fig.' 1. Figure 4 is a vertical cross-section of the drying kiln taken through the line e e, fig. 1. Figure 5 is a vertical cross-section of the furnace taken through the line ai? ce', g. 1. Similar letters of reference indicate like parts. i A i My invention has for its object to furnish an improved grain dryer by means of which grain may be thoroughly, evenly, and quickly dried. And it consists, first, in the combination of hollow rings and connecting pipes with each other and with a horizontal or vertical furnace for the purpose'of heating air to be forced. or

'driven irrto the drying krln, or fcreed-ei-dr-iven throughmtherings and connecting pipes' into the drying kiln;-

seeond, in the drying kiln, formed by combining-an interior revolving perforated cylinder, constructed with interior longitudinal anges or lifters, with the exterior, stationary, air-tight cylinders or drums, the whole being constructed and arranged as hereinafter more fully described.

A is the exterior drum or cylinder, which is stationary, and is supported in a slightly inclined position, as shownin g'. 2. This cylinder is made air-tight to prevent the escape of the heated air befoie it has passed entirely through the kiln or drying chamber A, and also to prevent the entrance of cold air to cool the kiln and retard the Vprogress of the drying. B is the interior cylinder, which may be made of perforated sheet metal or woven or netted wire, as may be desired or most convenient. This' cylinder` is securely attached to theends of the radial arms, b, which radiate from the shaft, C, to which they are rmly attached. These arms should be suilicient in number and sufciently near to cach other to support the cylinder B and vthe'grain which it may contain. The shaft C revolves in bearingsin the ends of the exterior cylinder A, as shown'in fig. 2, and motion may be given to it by any' convenient power. To the ends of the radial arms [11 are attached longitudinal strips or anges, b2, extending almost the entire length of the said cylinder B, as shown in iig. 2. These flanges b2, as the cylinder B revolves, act as liftcrs to carry the grain with them in their ascent and allow it to fall back through the heated air in the cylinder, thereby thoroughly stirring it and securing its being uniformly and levenly dried. To the edge of the forward or upper end of the cylinder B is attached a flange, b3, projecting inward to prevent the grain from flowing or falling back and getting between the cylinders B and A. The grain is introduced into the cylinder B through the feed-pipe, D, in the ordinary' manner, and after passing through the cylinder B, escapes, at the lower end of the cylinder A, through the pipe or spout, E; after which it is passed through another set of,cylinders constructed in the manner described, where it is exposed to a blast of cold air, cooling it and bringing it into a proper condition for storage. The furnace, F, may be a horizontal furnace, ns represented in the drawings, or it may be a vertical one, as the circumstances of each .case may render advisable. fis the grate, andfl is the hre-chamber of the furnace. Gr are hollow rings placed`in the furnace and connected together by the connecting pipes, II, as shown in figs. 3 and 5, that' is to say, if the induction pipe is connected with the lower part of the ring on -one side, the eduction pipe is connected with the upper part of the ring on the opposite side, so that the airmay be compelled to circulate through Ithe ring before escaping therefrom. rihe number of rings Gr employed and their size will depend upon the capacity of the i apparatus and the amount of work to be done. The air is introduced through the pipe I, and after passing through all the rings G, escapes through Athe pipe J, whence it is conducted through the pipe K, (shown in' red in tig. 1,) and xintroduced into the drying kiln through the pipe L. The passage of the air through the furnace and kiln should be accelerated by a bellows, fan-blower, or 'some `similar apparatus connected with either the pipes K or I, which may either cxhaustor force or blow the air through the furnace, and blow or force it through the kiln, by which means the rapidity of the drying is muchincreased. The air, after passing through the kiln,

escapes through the pipe M into the air, carrying with it the steam, 86e., that has been driven oi' from the grain.

Y 2 m The bellows, fan-blower, or similar apparatus, is also used to blow or force. the cold air through the drying kiln used for cooling the grain.

I claim as neuf, and desire to secure by Letters Patent- The hollow rings Gr and oonn'ectng pipes H, constructed as described, vin oombination with each other and with the furnace of a, drying kiln, suhstzintully- 'as described and for the purpose set'forth.
